It doesn't necessarily sound like a penile fracture - I think the results of that would be more dramatic than what you've described. However (and I'm not sure about this), it sounds like possibly there was some somewhat more minor damage, possibly penile bruising. I don't know what the treatment for that would be. If I were you, I'd definitely seek some medical evaluation. You could start with your regular Dr., describe what took place & the symptoms you're seeing now. He/she will probably ask you some additional questions about sexual history, if there have been any previous difficulties, bending, etc. & maybe if you've ever engaged in vigorous sex or masturbation, which could cause this kind of damage. If your regular Dr. isn't able to help, the next step would be to see a Urologist. It may turn out you just need some time to heal, but if it's more serious than that, I hope you get the right treatment & best wishes for a full recovery.
